Here's a GDB backtrace:

Program received signal SIGSEGV, Segmentation fault.
0x2b078fac in gcoOS_GetBaseAddress () from /usr/lib/libGAL.so
(gdb) bt

Backtrace stopped: previous frame identical to this frame (corrupt stack?)

Maybe I'm missing some piece, e.g. loading the video acceleration firmware?
n.b. I don't know much about this platform, so I'm a bit in the dark.
